ZF 5838.300.498 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 5838.300.498 REAR AXLE HOUSING is a critical structural component within heavy-duty construction machinery drivelines. This OEM genuine part serves as the rigid casing that encloses and supports the differential assembly, axle shafts, and final drive gears, ensuring precise alignment under extreme torque loads. The SKU 5838.300.498 is specifically designed to withstand high stress in ZF transmissions, acting as the primary load-bearing interface between the vehicle chassis and the wheel ends. Without this housing, the internal gear train cannot maintain proper mesh geometry, leading to rapid component wear.

Symptoms of Failure

• Visible oil seepage from axle tube seals: When the housing develops micro-fractures or warps from thermal cycling, lubricant escapes past the 0750117075: TAPER ROLLER BEARING seats, creating wet spots on the housing exterior.
• Persistent gear whine under load: A cracked or distorted housing allows the 5838109006: DIFFERENTIAL carrier to shift, causing uneven tooth contact and audible noise during acceleration.
• Axle shaft end-play exceeding 0.5mm: Bearing bore wear in the housing permits lateral movement of the 2095209037: DIFFERENTIAL assembly, detectable as a clunk when reversing direction.
• Metallic debris in differential oil: Spalling from the housing’s bearing journals contaminates the lubricant, often accompanied by a burnt smell from overheated 2095309059: DIFF.HOUSING components.

Technical Specifications

Compatibility

This rear axle housing is engineered for ZF’s WG series powershift transmissions commonly found in wheel loaders and telehandlers. It is a direct fit for the WG180 and WG200 transmission models, as well as the heavy-duty WG250 series. The housing also interfaces with ZF’s Ecomat 4HP and 6HP drivelines when used in articulated dump trucks. Always verify the axle ratio and differential case width before installation, as the 5838.300.498 is designed for single-reduction final drives with a maximum input torque of 8,500 Nm.
